Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

The fact that Polar Bears are extremely smart(as is all the bear family) and opportunistically feed on caribou, geese and eggs does not mean that all is well in their Arctic ecosystem............As Seals become less and less a dietary staple for the bears due to decreasing ice flows (climate change), the fact that the bears start dining on alternative foods will put pressure on the entire natural system(other carnivores, herbivores, plants et al?), likely sending ripple effects across a myriad of other plant and animal life..............There will be losers that result from the bears need to stary alive and it might take hundreds of years for this new system to rebalance itself under the new set of top down pressures that the bears are placing on the system

Polar bears to humans: 

Relax, we've got this

Polar bears may be more resilient to the effects of
 climate change than scientists had feared, according
 to a new study.

Do these Polar Bears really have a chance to survive
climate change even with their elastic dietary abilities?

Does the need to switch to alternate prey like goose and
Caribou impact other members of the bears system adversely?

The article above(click link to open) seems simplistic and
the researcher's hypothesis of the bears being able to adapt
under the melting of the ice seems extremely narrow to me
based on ecosystem science.............Your thoughts?
